Why do people always say 'nation-state' specifically in these cases, as well? Some of the richest states in the world aren't nation-states, like the UK.
I imagine because what they actually mean (state) gets ambiguous and confusing because of the united states, which are not really states in the same sense.
Can you clarify? I thought "nation state" was a fancy way of saying "country". Does it have a more specific meaning?
